One suspect was arrested Saturday morning on suspicion of armed robbery.
Matthew Booth, 18, of Saugus, was one of three suspects who allegedly approached a couple walking in the Bridgeport area around 10:15 p.m. and demanded the couple's money.
The couple told deputies that when they saw Booth had a gun, they gave up their cash, losing approximately $500.
Booth allegedly got into a car with the other suspects after taking the couple's money and sped off.
Deputies responding to an early morning party call Saturday saw a car matching the description given by the couple and pulled it over. Booth was in the car and was arrested.
He is being held on suspicion of armed robbery in lieu of $100,000 bail.
